Mageia 7: MGASA-2019-0346 Moderate: DjVuLibre DoS Threats

The updated packages fix security vulnerabilities:
In DjVuLibre 3.5.27, DjVmDir.cpp in the DJVU reader component allows attackers to cause a denial-of-service (application crash in GStringRep::strdup in libdjvu/GString.cpp caused by a heap-based buffer over-read) by crafting a DJVU file. (CVE-2019-15142)
In DjVuLibre 3.5.27, the bitmap reader component allows attackers to cause a denial-of-service error (resource exhaustion caused by a GBitmap::read_rle_raw infinite loop) by crafting a corrupted image file, related to libdjvu/DjVmDir.cpp and libdjvu/GBitmap.cpp. (CVE-2019-15143)
In DjVuLibre 3.5.27, the sorting functionality (aka GArrayTemplate::sort) allows attackers to cause a denial-of-service (application crash due to an Uncontrolled Recursion) by crafting a PBM image file that is mishandled in libdjvu/GContainer.h. (CVE-2019-15144)
DjVuLibre 3.5.27 allows attackers to cause a denial-of-service attack (application crash via an out-of-bounds read) by crafting a corrupted JB2 ima...
